Thank you phoerious for your comment, but I don't find meaning to change temp directory on keepassxc settings. |

Externally opened attachments are now lifecycle-managed properly. The temporary files are created with stricter permissions and entirely random names (except for the file extension) to prevent meta data leakage. When the database is closed, the files are overwritten with random data and are also more reliably deleted than before. Changes to the temporary files are monitored and the user is asked if they want to save the changes back to the database (fixes #3130). KeePassXC does not keep a lock on any of the temporary files, resolving long-standing issues with applications such as Adobe Acrobat on Windows (fixes #5950, fixes #5839). Internally, attachments are copied less. The EntryAttachmentsWidget now only references EntryAttachments instead of owning a separate copy (which used to not be cleared properly under certain circumstances).

Overview
When I open a pdf file attached on an entries, Acrobat make error that the file is already open by an other user.
When I looking for temporaty file on my profil AppData\Lacal\temp, I see different files with the same name but some new carraters behin. That is to say, with this error, temp file are not cleaned at the end of open process.
If I open an other type file (.csv for exemple) it is on redead only mode. I can't modified then.
I am on window10 And keppassxc.exe is allowed to acces to all files.
If I open with Keepass2 that is OK
Best regards
Expected Behavior
File must be open en clean at the end in Appdat/Local\Temp
